This video may not really be 100% specific to Minetest, but it's been requested quite a bit, and who am I to refuse the fans what they want to see? I'll be going over the basics of using Github on Linux in this video. From what I've been told Windows is rather different, so I don't know how much of this information is going to be relevant if you are on Windows.

This video was recorded before M$ bought out Github. There are several alternatives if you want to avoid the death grip of M$. notabug, repo.or.cz, gitlab.
